- Watch: Video report from ITV Wales reporter Mike Griffiths
Wales is the worst in the UK for access to 4G signal, according to consumer magazine Which?
They found users were only able to connect to 4G 35.4% of the time, and that Cardiff is one of the worst big cities nationwide for 4G signal, with Wales as a whole lagging behind London.
The report found Middlesborough is the best UK city for 4G accessibility, with 83% availability, while London came in 16th, with Nottingham, Cardiff, Southampton and Bournemouth rounding out the list of 20th biggest UK cities.
The average overall network availability across the UK is 65%, meaning mobile users can access 4G almost two thirds of the time.
This isn't as good as many other countries, and ranks the UK at 54th in the world, behind Estonia and Peru.
